Biaryls play an important role in numerous areas of chemistry. The biaryl structure is wide-spread across many classes of natural products, and many of them have interesting biological activities. 1 Furthermore, compounds with biaryl moieties have found broad application as catalysts in asymmetric synthesis. This is based on the often hindered rotation around the aryl–aryl single bond and the atropisomerism resulting from this. 1,1′-Binaphthyls, especially, have ...
